Food Safety: Pathological and Biochemical Responses of Nile Tilapia (Oreochromis niloticus) to Parasitological Infestation and Heavy Metals Pollution in Aquaculture System, Jeddah, Saudi Arabia

Abstract

This study is recognized as the first to address the food safety of farmed tilapias in Jeddah, Saudi Arabia. The results emphasized a significant relation between parasites and heavy metal in disrupting fish defense systems and harming fish's physiological homeostasis and the histological state of tissues. The parasitized and polluted farmed fish pose health risk to humans due to possible zoonosis from parasitic infections and its subsequent bacterial infections with long-term exposure to toxic chemicals. Addressing the need for a combination of improved aquaculture practices, and stringent regulatory oversight.
